Indications for Tissue Expansion
Tissue expansion is recommended when local tissues are insufficient to reconstruct a defect or when large areas of skin require restoration.
Common indications include:
- Post-burn skin defects
- Traumatic soft tissue defects
- Large postoperative defects
- Reconstruction following tumor removal
- Congenital skin defects
- Scar contractures and deformities
- Closure of extensive wounds
- Reconstructive surgery of the scalp, face, and neck
Scalp tissue expansion and lateral neck expansion are particularly valuable because they preserve the natural color, texture, elasticity, and hair-bearing characteristics of the skin.
Types of Tissue Expansion
Acute Tissue Expansion
Acute tissue expansion is performed during a single surgical procedure.
Using specialized surgical devices, the surgeon gradually stretches the wound edges, allowing the defect to be closed without skin grafting.
This technique is most effective for:
- Small defects
- Medium-sized defects
- Areas with sufficient skin elasticity
Tissue Expander Reconstruction
Tissue expander reconstruction is one of the most effective techniques for repairing extensive skin defects.
A specially designed tissue expander is placed beneath the skin and gradually filled with sterile saline over several weeks or months.
As the expander slowly enlarges, new skin is generated, providing sufficient tissue for definitive reconstructive surgery.
